Hello,

I contact to you because a customer us interested on the part number #nRF52811, and they made the following questions, forwarded from our customer service representative;

 

“Customer is looking for a device for a real-time monitoring of test samples.

For example Bluetooth 5.1 and its new Angle of Arrival and Angle of Departure functions, which could to locate devices with this new version of Bluetooth 5.1. by trilateral triangulation.

 

Customer's development laboratories  are located in a four-story building each floor of approximately 100 m2.

There are approximately 50 pieces of test samples customer needs to monitor in each time.

 

Can we recommend a device (for example Nordic Semiconductor nRF52811) for a real-time monitoring?”

 

Please could you assist us?

Is correct what the customer is looking for? Or is it better another one?

Thank you very much for your support and kind regards,

Hi Miguel

The nRF52811 or the nRF52833 would be the best fit for this use case.  Both devices support BLE direction finding (AoA and AoD). The main difference between the two devices is that the nRF52833 has bigger RAM and Flash Memory, and can, therefore, support larger applications. So depending on the size of the intended application they should choose one of these devices. The nRF52811 should be sufficient for a basic real-time monitoring application.

As of yet, we do not have any examples for hardware (where an antenna array will be necessary) or software projects for direction finding I'm afraid, so the support we can provide is limited.

Best regards,

Simon
